I took FOR408 at SANS CDI in December.  My studying consisted of reading each book cover-to-cover and highlighting things of interest.  I used 35 post-it tabs and created an "index" that divided all the contents into 35 sections.  It was much less detailed than most indexes I've seen, but it worked for me.  After scoring 81% and 83% on my two practice exams, I scored a 91% on the actual exam! 

  I did each practice exam in under 2 hours, so I slowed down on the actual exam (2 hrs 25 mins).
Overall, a great course and glad to have my first GIAC cert.  Now, I have a weekend to recover before SEC504 vLive begins next week!
